Wine Glossary: Terms Every Wine Lover Should Know
The world of wine comes with a rich vocabulary – a mix of French loanwords, technical terms, and tasting descriptors that can feel overwhelming at first. But you don't need to learn everything at once. This wine glossary collects the most important terms, from basic tasting vocabulary to classification systems and storage concepts. Use it as a reference when you're reading about wine, shopping for bottles, or taking notes in your wine diary on Macave.
A
Acidity
One of the fundamental building blocks of wine. Acidity gives wine freshness, liveliness, and balance. Wines with high acidity taste crisp and mouthwatering. You'll feel it most along the sides of your tongue and in your jaw. See also crisp.
AOC / AOP
Appellation d'Origine Contrôlée / Appellation d'Origine Protégée. The French (and EU) classification system regulating where grapes may be grown, which varieties are permitted, and how wine is produced. It guarantees geographic origin but not necessarily quality. Other countries have equivalent systems – see DOC and DO.
Aroma
The scents and flavors that come directly from the grape and early winemaking. Young wines are dominated by aromas (fruit, flowers), while aged wines develop more bouquet. See also bouquet.
B
Barrique
A traditional French oak barrel holding 225 liters. Used for fermenting and aging wine. New barriques contribute more obvious flavors of vanilla, toast, and spice, while older barrels have a subtler influence.
Biodynamic
A farming philosophy based on Rudolf Steiner's teachings that goes beyond organic agriculture. In addition to avoiding synthetic chemicals, biodynamic growers work according to cosmic calendars and treat the vineyard as a self-contained ecosystem. Certified by organizations such as Demeter.
Blanc de blancs
"White from whites" – sparkling wine made exclusively from white grapes, typically chardonnay. Most common in Champagne. These wines tend to be elegant and fresh.
Blanc de noirs
"White from blacks" – sparkling wine made from red grapes (usually pinot noir and pinot meunier) where the skins are separated early to prevent the wine from taking on color.
Body
How heavy or light a wine feels in your mouth. Usually described as light, medium, or full-bodied. Body is primarily influenced by alcohol level, extract, and tannins. A helpful analogy: skim milk (light body), whole milk (medium), cream (full body).
Bouquet
The more complex aromas that develop as wine matures in barrel and bottle – think leather, tobacco, mushroom, or dried fruit. Unlike aroma, bouquet comes from aging rather than from the grape itself. See also aroma.
Brut
A designation for dry sparkling wine with a maximum of 12 grams of sugar per liter. Within Champagne and other sparkling wines, there's a scale from Extra Brut (very dry) through Sec, Demi-Sec to Doux (sweet).
C
Cork taint (TCA)
A wine fault caused by the chemical compound trichloroanisole (TCA), which can form in natural cork. Corked wine has a musty, damp smell reminiscent of wet cardboard or a moldy basement. TCA destroys a wine's fruitiness but is harmless to drink. An estimated 2–5% of all wines with natural cork are affected.
Crisp
A tasting term for wine with noticeable, refreshing acidity. Crispness gives wine energy and makes it appetizing. Often associated with citrus notes in white wines. See also acidity.
Cru
A French term referring to a specific vineyard, village, or quality class. In Bordeaux, Grand Cru Classé designates the top estates. In Burgundy, cru refers to specific vineyard parcels (climats). In Champagne, entire villages are classified as Grand Cru or Premier Cru.
Cuvée
Means "blend" and refers to the specific combination of grapes, vintages, or lots that make up a wine. In Champagne, a house's prestige bottling is often called its cuvée de prestige or tête de cuvée.
D
Decanting
Pouring wine from its bottle into a carafe. This serves two purposes: separating wine from any sediment, and exposing it to oxygen so aromas and flavors can open up. Older red wines are typically decanted gently for sediment, while younger wines may be decanted more vigorously for aeration.
DO / DOCa
Denominación de Origen / Denominación de Origen Calificada. Spain's wine classification system. DOCa (sometimes DOQ in Catalan) is the highest tier, awarded only to the most prestigious regions such as Rioja and Priorat.
DOC / DOCG
Denominazione di Origine Controllata / Denominazione di Origine Controllata e Garantita. Italy's classification system. DOCG is the top level, with stricter regulations and mandatory tasting of every batch.
Dry
Wine with very little or no residual sugar – the sugar has been almost entirely fermented out. Most red wines and many white wines are dry. The opposite of sweet. Note that fruity and dry are not mutually exclusive – a wine can be completely dry yet taste very fruity.
E
Enology (Oenology)
The science of winemaking. An enologist is a trained winemaker with an academic degree in the subject.
F
Fermentation
The process by which yeast converts grape sugar into alcohol and carbon dioxide. Primary fermentation creates the wine itself. Sparkling wines often undergo a secondary fermentation (either in bottle or in tank) that produces the bubbles.
Fruity
Wine with noticeable fruit aromas and flavors. Fruity doesn't necessarily mean sweet – a dry wine can be very fruity. White fruity wines often show citrus, apple, or tropical fruit. Red fruity wines lean toward berries, plum, or cherry.
Full-bodied
A wine with high flavor concentration and weight in the mouth. Full-bodied wines often have higher alcohol and powerful character. The opposite of light-bodied. See also body.
G
Grand Cru
"Great growth" – the highest classification in Burgundy and Champagne. In Bordeaux, Grand Cru Classé has its own history and hierarchy established in 1855 (and barely changed since). Regardless of region, Grand Cru signals the absolute pinnacle of a wine-growing area.
Grape variety
The specific type of wine grape used to make a wine. Common red varieties: cabernet sauvignon, merlot, pinot noir, syrah/shiraz, nebbiolo, sangiovese. Common white varieties: chardonnay, sauvignon blanc, riesling, chenin blanc, grüner veltliner.
L
Lees
Sediment consisting of dead yeast cells and other particles that settle after fermentation. Some winemakers age wine on its lees (sur lie) to add complexity, richness, and breadth. Common in Champagne and Muscadet production.
M
Maceration
The process by which grape juice sits in contact with skins, seeds, and sometimes stems to extract color, tannins, and flavor compounds. Longer maceration produces darker, more tannic wine. Carbonic maceration (macération carbonique) is used in regions like Beaujolais.
Magnum
A bottle holding 1.5 liters – twice the volume of a standard bottle. Wine in magnums is thought to age more slowly and harmoniously, making it a popular format for wines intended for long aging.
Malolactic fermentation
A secondary process where sharp malic acid (think green apples) is converted into softer lactic acid (think dairy), making wine rounder and smoother. Sometimes called "malo" in wine slang. Nearly all red wines undergo malolactic fermentation; for white wines, it's a stylistic choice.
Minerality
A debated tasting term describing flavors in wine reminiscent of stone, chalk, salts, or seawater. Scientists debate whether minerals actually transfer from soil to wine, but the term is well-established for describing a certain fresh, non-fruity character.
N
Natural wine
Wine made with minimal intervention – typically organic or biodynamic grapes, spontaneous fermentation with wild yeast, and very few or no additives (including minimal sulfur). There is no official certification for natural wine, and the definition varies.
Négociant
A wine merchant who buys grapes, must, or finished wine from growers to blend, age, and sell under their own label. Common in Burgundy and the Rhône Valley.
O
Oak aging
Aging wine in oak barrels, which adds flavors of vanilla, toast, coffee, and spice while making the wine rounder and more complex. American oak typically gives stronger vanilla notes, while French oak contributes more subtle spice and coffee. Aging time varies from a few months to several years.
Oxidation
When wine is exposed to oxygen and changes as a result – the color browns, fruitiness fades, and flavors become flat or vinegar-like. Unintentional oxidation is a wine fault (see cork taint), but controlled oxidation is used deliberately in styles like sherry, Madeira, and certain natural wines.
P
Pétillant naturel (Pét-nat)
Sparkling wine made using the "ancestral method" – the wine is bottled before primary fermentation finishes, and carbonation occurs naturally. Unfiltered and often cloudy. Has become very popular within the natural wine movement.
Premier Cru
"First growth" – a quality classification. In Burgundy and Champagne, it's the second-highest tier (below Grand Cru). In Bordeaux, it's the very highest tier (the five famous Premiers Crus from the 1855 classification).
R
Reduction
A wine fault that produces smells of struck match, rubber, or rotten eggs, caused by sulfur compounds. Mild cases often dissipate after decanting. See also decanting.
Reserva / Riserva
A designation indicating longer aging than standard in Spain and Italy respectively. In Rioja, a Reserva must age at least three years (with at least one in oak). In Italy, requirements vary by region and wine type.
Residual sugar
The amount of grape sugar remaining in wine after fermentation. A wine with less than about 4 grams per liter is generally considered dry. Higher residual sugar results in off-dry, semi-sweet, or sweet wines. Abbreviated RS.
S
Sediment
Natural deposits that form in wine during aging, consisting of tannins, color pigments, and tartrate crystals. Completely harmless but can taste gritty – which is why older wines are often decanted. See also decanting.
Sommelier
A trained wine professional who specializes in wine service, typically at a restaurant. A sommelier helps guests select wines, manages the wine list, and ensures proper serving.
Sparkling wine
Wine with carbon dioxide – everything from Champagne and Cava to Prosecco and Pétillant Naturel. The bubbles are created either through a secondary fermentation in bottle (traditional method) or in tank (Charmat/tank method).
Sulfites (sulfur dioxide)
An additive used as a preservative in wine to prevent oxidation and unwanted fermentation. Nearly all wines contain sulfites – either added or naturally formed during fermentation. The label statement "contains sulfites" is required when levels exceed 10 mg/l.
T
Tannins
Natural polyphenols found in grape skins, seeds, and stems, as well as in oak barrels. Tannins create a dry, astringent sensation in the mouth (think strongly brewed black tea) and contribute to a wine's structure, complexity, and aging potential. Over time, tannins soften. Found primarily in red wine.
Terroir
A French concept with no exact English translation. Terroir is the unique combination of soil, climate, topography, altitude, and human traditions that make wine from a specific place taste the way it does. It's the core of European wine philosophy.
V
Vinification
All the steps in winemaking after the harvest – pressing, fermentation, aging, fining, and bottling.
Vintage
The year the grapes were harvested. Vintage affects a wine's character because weather conditions vary from year to year. Some vintages are widely considered superior in a given region. Non-vintage wines (NV) are blends of multiple harvest years – common for sparkling wine.
Viticulture
Everything related to grape growing – pruning, irrigation, pest management, harvest decisions. A viticulturist has an academic degree in grape cultivation.
W
Whole-cluster fermentation
Fermenting grapes with their stems intact rather than destemming first. This technique can add spice, herbal complexity, and a certain freshness to red wines. Common in Burgundy and increasingly popular with Syrah producers.
